Small Molecule Inhibitors in Drug Discovery and Development

# Small Molecule Inhibitors in Drug Discovery and Development

Introduction to Small Molecule Inhibitors

Small molecule inhibitors have become indispensable tools in modern drug discovery and development. These compounds, typically with molecular weights below 900 Daltons, are designed to specifically target and modulate the activity of proteins involved in disease pathways. MuseChem offers a comprehensive collection of high-quality small molecule inhibitors that are widely used in pharmaceutical research and development.

Mechanism of Action

Small molecule inhibitors work through various mechanisms to interfere with protein function:

  • Competitive inhibition at active sites
  • Allosteric modulation
  • Protein-protein interaction disruption
  • Enzyme co-factor competition

These inhibitors can be reversible or irreversible, depending on their binding characteristics and the desired therapeutic effect.
